Observing Massive Galaxies at high-redshift with the Gemini Deep Deep Survey

Karl Glazebrook

The Gemini Deep Deep Survey is an IR selected spectroscopic survey for massive galaxies with reasonable completeness to z=2 and extensive ACS imaging. We find an abundance of massive galaxies, both red/quiescent objects similar to local ellipticals and equally abundant massive star-forming galaxies which are absent in local samples. I report on recent results on the evolving mass density of galaxies over 1
